I do hereby declare that the following is a full, clear, "and leXact description of the` same.

i The present invention consists essentially 'of different ously or jotherwise, posed in relation movable from said stock.

Thegprincipal object of the invention is devise a gun having two barrels, one be- `carrying two `guns-and reducing .the additional weight.

"A further object of the 'invention is topro- [vide arepeater gun having a simple lock ,j mechanism and whereby the barrels, which Aareone above the-other, may be, when desired, Linterchanged in their-positions.

' A horizontal plunger rod is provided in the hole or spring chamber 3 inthe lock casing 5, and 44 is a crosshead bent to avoid the firing pins 27 and 28' and 451s a f' spiral spring adapted tohold said rod nornially in its forward position. VAt right anerably integral therewith, a lever 46 which fis adapted to normally engage Vsaid vertical gles to said plunger rod 43'is provided, prefslot 4. `The said leverwhen operated is turned outv of engagementwith the slot 4 and'pulled rearwardly into the slot 3 there-` by carrying the vrod 43 and the head 44 rearward. -The breech block 19 that isV engaged "(as shown in the drawings) vwith saidhead 44 by thejhook or the bar 435jwillbe carried F out of the chamber or casing 17. When'the lever 46 is released, the tension spring 45 will carry it back into its normal position,
